Mono Monday Challenge: Bigger

This is my Jigger; a device intended for measuring spirits.  One side is 25cls, the size of a standard pub measure, while the other side is bigger at 50cls, the size of a 'double'.  I tend to use the jigger when pouring drinks as it is easy to pour a very large measure if trying to guess the size.  However, to the best of my knowledge, the 'single' side of this has never been used. Only the Bigger Jigger.

Thanks to TheAphid for hosting the challenge again this week.
